Kernel flows typically expire five seconds after being idle. (It may be
shorter if under load.)

I am trying out openvswitch 1.4.0 with the upstream 3.3.0-rc2 kernel.
I removed the default table flow table entry and added the following 2
flow table entries matching the br0 mac address as dl_src or dl_dst
# ovs-ofctl del-flows br0
# ovs-ofctl add-flow br0 idle_timeout=0,dl_src=00:1b:21:84:4e:
Jesse,
To add to Juan's points, we are not power users of OVS. All we need is a
DMAC based switching of packets paying attention to VLAN ids.
Short lived/long lived flows happen at L4 level which we don't want OVS
to pay attention to.
Is this possible ? Is it possible to run OVS in bridge mo

We do not see the same problem with the Linux Bridge, and we want to use the
vswitch.
Is it possible that ovs disrupts long living TCP connections in the presence of
many

What's the traffic mixture like when you have this problem with vlans
(i.e. single flow vs. many connections)? If you run a single stream, what
is the ratio of hits to misses on the relevant datapath?

The easiest solution might be a new version of the brctl wrapper that
OVS used to install on XenServer:

I did some more tests, and so far it looks it's only the brctl show that
has this problem.
